subiemech85 Posted January 18, 2006 Share Posted January 18, 2006 that's right I filled up on 105 octane 85% ethanol timing set at 20*, ambient air temp 30* has low power below 4k occasionally, it wants to cough, sputter, and slowly loose speed when floored, so I have to downshift any suggestions??????

WagonsOnly Posted January 18, 2006 Share Posted January 18, 2006 Run it on 91 or 93, I know you're from Iowa, but no ethanol would help. I got 17MPG in a New Beetle (I usually average around 35 hwy) using E85 for all highway driving. Didn't realize what I'd put in it 'til I read the receipt. (This was in your home state...)

NoahDL88 Posted January 18, 2006 Share Posted January 18, 2006 Umm, drain the tank and start over. really Ethanol, E85 burns at 6:1 air fuel ratio, Gasoline burns at 14:1, so as i'm sure you can figure out, it is running uber lean. Its also eating away at your rubber lines and seals. find a friend with a ford with the leaf logo on it, and transfer the tank. Really, this is bad for your engine.

tizzle Posted January 18, 2006 Share Posted January 18, 2006 My RX runs better on plus, than on supreme. I can imagin that it would run much worse on 105 Link to comment Share on other sites More sharing options...
subiemech85 Posted January 18, 2006 Author Share Posted January 18, 2006 but dad's nissan 200 sx with the vg30 6cyl used to run just fine with E85 on a totally unrelated topic, it has a busted crankshaft, not bad after 250k+ but along that line, it's the second crankshaft he broke, the first being a cadillac highly troubled 4.1 I figured that the E85 wouldn't be too bad, as I was having similar but less obvious problem running E10 89 I figured that the 11g I added to the 5g of "regular" should help clean things out it was cheap, $1.78 vs. $2.10 as long as I can run 70+, I'll be fine btw, how does E85 compare to "race gas" Link to comment Share on other sites More sharing options...
CHIM Posted January 18, 2006 Share Posted January 18, 2006 i used to run my GL-10 turbo on reguler fuel, on a wim i put the premium in it and have never went back, loves the stuff, all my carbed cars never saw a difference. Here in oregon our fuel doesn't have ethenayl, bud stuff for a motor, it's an alcahol additive to save them money and make you spend more money on maintainence. ~Dayten~ Link to comment Share on other sites More sharing options...
NoahDL88 Posted January 18, 2006 Share Posted January 18, 2006 Ethanol is a plant alcohol that is derived predominatly from corn. It burns much cleaner, and is theoretically a renewable resource with which we can replace gas, as long as every square inch of the US is converted to corn production. Race gas is Leaded gas, like what the old blues mobile ran on, it isn't streat legal and it will ruin your cat converters. The octane may be the same, but they are two unrelated fuels. leaded gasoline still burns at a 14.7:1 ratio, where as i had stated E85 burns at 6:1 Super high-po racing gas is Methanol, but thats just for funnycars, and top fuel dragsters. On the subject of Octane, If your car is designed for regular and you do nothing to the car but put in premium, it will do nothing for performance, and fuel economy will suffer. Its a longer hydrocarbon chain that does not have more engergy per unit size, it just resists detonation better. I don't care if you have a friend of a friend who did this and got fantastic results, cause he's lying. On the other hand, if your car takes premium, you'd better stick with it, or you'll detonate, or at the least, your computer will retard your timeing to the point where you'll forget you have that turbo.

LPGsuperchargedBrumby Posted January 18, 2006 Share Posted January 18, 2006 ethanol's fuel/air ratio is 9:1 menthanol's 6:1 petrol's 14.7:1 LPG 15.8:1 diesels F/A ratio changes from 60+:1 at idle to as low as 8:1 under full power+heavy load Link to comment Share on other sites More sharing options...
Do It Sidewayz Posted January 18, 2006 Share Posted January 18, 2006 Race gas is Leaded gas, like what the old blues mobile ran on, it isn't streat legal and it will ruin your cat converters. not all race gas is leaded! I have like 40 liters of 114 Octane race fuel sitting in my garage...it's unleaded! I run this stuff in my 85 RX rally car, and it loves it!!!

zyewdall Posted January 18, 2006 Share Posted January 18, 2006 Sounds like it's just running way too lean because of the oxygenated fuel. For reasons that I don't understand, this isn't good for gas engines. Can you reprogram your ECU with a new fuel/air curve? That's apparently what all the cars in Brazil do (about 80% of them down there run on E85 or maybe E100 now) I wish I could buy E85 here...

Researchers are working on new production techniques to make it from cellulose instead of sugar, which give alot more ethanol for given inputs of feedstock and fossil fuel energy to refine it. BTW, Brazil gets all of it's ethanol from sugar cane, and up in Seattle, I understand they get a bit of it from the papermills (not that that is sustainable either....)
